You can do the same, or other stuff! You need a mol file to input, for example I took the mol file of the 9_quine from here. You can pick from lots of them (not guaranteed all of them work yet in the editor, especially those with “bb” in the name), from the chemlambda collection of molecules.
Is much much better than the animation made by hand
I look forward for a convergence with hapax, it would be nice to make a gamelike “feed the quine” where you have the “tokens” which make the reactions happen and you feed them with the mouse to the quine, etc.
UPDATE: this time I used bigpred-train and I let it reduce automatically, gives this psihedelic
